Multi-photon 3D laser printing, also known as direct laser writing (DLW), has revolutionized the fabrication of complex microstructures. A new review by co-first authors Cluster Young Scientists Philipp Mainik and Christoph Spiegel as well as PI Eva Blasco highlights recent advances in the field, with a focus on the use of active materials. The review published in Advanced Materials provides a comprehensive overview of the latest advances and challenges, and it offers insights into the future of the field, covering a wide range of topics, including applications in microrobotics, optics and photonics, microfluidics, and life sciences.
